SHINGLE ROOF.

Specification of Letters Patent.

Patented Feb.l 15, 1921.

Application led February 11, 1920. Serial No. 357,935.

To all whom t may concern:

Be it known that I, WILLIAM WALTER Lnvis, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Shingle Roofs; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in shingle roofs composed of so-called asphaltic shingles, and has for its main objects to provide a roof of this character which presents a very ornamental appearance and also one in which the shingles are so overlapped as to substantially prevent fiapping thereof in the wind.

The invent-ion consists further in the construction of thc shingles per se composing the roof, and one of the objects of the invention is to provide a shingle of this character which is so constructed as to render it relatively inflexible and heavy so as to prevent flapping thereof under the iniiuence of high winds when laid.

The invention is illustrated in the accompanying drawings in which:

Figure l is a fragmentary view in elevation of a portion of a shingle roof constructed in accordance with the invention.

Fig. 2 is a central longitudinal section of a shingle constructed in accordance with the invention.

Fig. 3 is a fragmentary view similar to Fig. -1- illustrating a modified form of construction of the shingle and a roof composed of the same.

Asphalt shingles have been found somewhat unsatisfactory for the reason that they are made of a very flexible paper usually known as wool felt impregnated and coated with asphaltum and coated on one face with comminuted mineral such as crushed rock ranging in mesh from 14 to about 30. The comminuted mineral is intended in the first place to impart color to the shingle, and in the second place to increase the weight thereof and afford a protective coating over the weather face thereof. It has been found, however, that these shingles are so fiexible that they readily yield to high winds and Hap and break off so that the roofs composed thereof are not very long lived. The object of. the present invention is to provide a. shingle of the character defined which is rendered relatively inflexible and resistant to fiapping and high winds by a new mode of construction, and which furthermore, is at the same time rendered Very ornamental so that roofs composed thereof will present a more pleasing appearance.

The shingle of my invention is composed of a strip or sheet A of paper which is impregnated in the manner common to asphalt roofings with asphaltum and also coated with said substance on both faces, the coatings being indicated at B and C. While these asphaltic coatings are still soft and very adhesive a relatively coarse comminuted material ranging from about 12 to 20 mesh is applied to both said coatings B and C, and becomes partially embedded therein. The color of the grit on the weather face of the shingle applied to the coating B is preferably very dark and black and is the best to employ. After these layers of grit indicated at D and E respectively, have become partially embedded in the coatings, and the latter has become partially set, there is applied to one end of each shingle, and preferably of substantially onethird of its area, a second coating F of asphaltum, and while this coating F is still relatively soft and adhesive a layer G of grit of a light color contrasting with the color of the layer E is applied thereto; this grit being also preferably very coarse so as to add as much weight as possible to this end of the shingle. The completed shingle thus presents a structure havlng a part of its surface covered on one face with a continuous layer of grit, and the opposite or weather face covered in part with a similar layer of grit, and in part with two layers of the same and an additional coating of asphaltum.

From the standpoint of ornamentation the completed shingle presents a rectangular surface. the larger part of which constituting substantially a square, is covered with a very dark colored or black grit, and the remainder of its surface of oblong shape covered with grit of a very light color. The light colored area constitutes the main portion of that part of the shingle which is exposed to view and weather, and by reason of the fact that it is rendered very heavy, and also relatively inflexible by the multiplicity of layers or coatings of asphaltum and grit applied thereto, it will not readily yield to high winds to cause it to flap on the roofs. In laying shingles-itis customary to begin at the eaves of the roof and nail down a row of shingles, the nails being preferably applied over the upper twothirds of 'the area thereof.

rThe next higher row of shingles isthen laid in staggered relation to the first row, and so as to overlap substantially two-thirds ofthe area of the first row, this operation being repeated to the ridgeof theroof.

Iii-laying the shingles of my present invention each additional row is laid to not entirely overlap the dark colored surface of the next lower row, but to leave a very narrow strip of the darker surface immediately above the light surface exposed to View to simulate the shadows cast by wood shingles. rIhus the finished roof presents a horizontally striped appearance which is very pleasing to the eye. In this way also only the heaviest part of the shingle practically is exposed to view and to the action of the wind.

VThe shingles may be modified in construction to correspond to F ig. -3- in which the light colored grit area extends from the left hand edge of the shingle to a point contiguous to the right hand edge, so that when two of said shingles are laid side by side there is a strip of black or other dark surfacing visible between adjacent lighter surfacings.y In laying these shingles in the staggered relation and otherwise, the same as above described, the completed roof will present an appearance similar to the view in side elevation of a brick wall.

By means of my invention I attain two advantages simultaneously, namely: improvement in construction ofthe shingles and improvement in the appearance of the roof covered therewith, both these advantages being obtained at very small expense.

It will be readily understood also that instead of cutting the shingles as shown in the drawings, each shingle strip may consist of three or four shingle widths, or in other words, each strip may be a gang7 shingle composed of as many shingle-widths as desired.

I claim as my invention:

l. A roof composed of shingles each comprising a rectangular sheet of a fibrous material having coatings of asphalt and surportion thereof adjacent the double surfaced area, whereby narrow stripes of a color contrasting with that of the second surfacing are exposed to view together with said double surfaced areas, the latter being rendered heavy by the double surfacing for resisting wind.V

2. A shingle comprising a rectangular strip of a fibrous material coated withV asphalt and surfaced with coarse mineral grit on both its faces, that portion ofthe shingle adapted to be exposed to ,view provided withV a second coating of asphalt and a second surfacing of coarse grit of a color contrastlng with that of the primary surfacing, the

second surfacing covering a rectangular area s extending from two transverse edges of the shingle and being of less area than 'the total exposed portion of the shingle whereby stripes of a color contrasting in color withV the second surfacing are exposed to view on the finished roof. Y

3. A shingle comprising a rectangular strip of a fibrous material impregnated and coated with asphalt and surfaced with mineral grit over the whole of both faces' for rendering the shingle heavy and unyielding, and a second coating of asphalt and a second surfacing of grit of a contrasting color with that of the primary surfacing, the second surfacino` covering a rectangular area on the weather end of the shingle which is of less area than said weather end, and which adds to the weight and rigidity of said end.
